Top Stories: A New Dolphin Species, Why Not to Fight a Fever, and Earth's Life Expectancy
In the Amazon Basin, local legends claim that it's bad luck to kill a river dolphin. But that's not the only reason to protect these animals. Researchers recently identified a whole new species of river dolphin in Brazil—and discovered that each species of river dolphin is much rarer than we thought.
Good news, everyone! New studies show that the sun won’t vaporize our planet's water for at least another 1 billion to 1.5 billion years—hundreds of millions of years later than we thought. The findings won’t change your retirement plans, but could imply that habitable, Earth-like alien worlds are more common than scientists thought.
A pair of researchers has used a simple epidemiological model to track the use of Facebook and found that it has spread just like a contagion. Moreover, their model suggests that, just like Myspace before it, Facebook will suffer a colossal fall within the next few years.
This week, the European comet-chasing probe Rosetta successfully roused itself from a 2.5-year sleep and signaled anxious controllers on the ground. Rosetta has traveled 6.2 billion km in an attempt to do something never done before: to catch up with a comet, 67 P/Churyumov-Gerasimenko, as it speeds toward the sun and to go into orbit around it.
